Intersection between `z.object` and `z.record` incorrectly merges validators
When intersecting a z.object and a z.record, zod applies validators for the keys and values of the record to the rest of the object.
const ConfigSchema = z
.object({
name: z.object({
first: z.string(),
}),
})
.and(
z.record(
z.enum(['a', 'b']),
z.object({
sub: z.string(),
})
)
);
const validInput: z.infer<typeof ConfigSchema> = { // typescript type is correct and doesn't complain here 👍
name: {
first: '',
},
a: {
sub: '',
},
};
ConfigSchema.parse(validInput);
// ^ this throws 2 errors because:
// 1. 'name' doesn't match ['a', 'b']
// 2. 'name.sub' is required (even though this will never exist)
Reproduction URL: stackblitz.com
Expected behavior: validators for record keys and values should only apply to the record.
The same problem occurs with intersections of records that have native enum keys and template literal keys (eg. [key: dynamic/${string}]).
